ABSTRACT:
To provide for circumferential register adjustment of a printing cylinder, for example a plate or forme cylinder (1) of a printing machine, in which the cylinder is eccentrically retained in an eccentric bearing (5, 6, 7) to permit throw-off of the cylinder from an engaged cylinder, such as a blanket cylinder, a circumferential register adjustment positioning shaft (8) is threadedly secured to a counter plate (13), attached to the frame of the machine. The positioning shaft is coupled via an eccentric bushing (18) to the drive gear (3) of the cylinder. The eccentricity of the eccentric bushing, and the eccentricity of the eccentric bearing (5, 6, 7) for the cylinder are the same, and the eccentric bushing and the eccentric bearing are coupled together by a coupling rod (23) and an extension (25, 25) on the eccentric bushing. Bearings permit both relative rotation, eccentric rotation, and axial shift of the drive gear under control of the positioning shaft.
